Limits of graftage. Theoretically botanists and nurserymen have limited graftage to the exogens, plants which have a cam- bium layer in a definite re- gion beneath a bark layer; for the process depends upon the intimate union of it is alwa)'s sharply defined from the remaining portion (xylcni, 2().'i) ])y a layer of cambium. The mner bark is derived from the phloem, the wood from the xylem. The elaborated plant food from the leaves passes down and is distributed by the phloem. 203.
